I'm trying to do a cascading dropdown where the first choice allows for multiple selections and then based off of that it populates the second choice which just has to allow for one selection from a list. Is there a way to do this in 2013?
For an example:
We have multiple systems that a counterparty may need to be setup in. On the request form, I need the user to be able to select one or more systems (Trading System1, Trading System2, Accounting System, all, 1 and 3, etc.). Once the system is selected, the 2nd field of Counterparty Type should filter based off of the selection(s) for System. Some systems don't have any Counterparty Type associated with them and others do. So, if the 2 systems that have Counterparty Type associated with them are ever selected, then the list needs to populate with those fields regardless of what other systems are selected. If neither of the 2 with Counterparty Type are selected then the box would be blank.
Has anyone ever dealt with this before?
